Análisis comparativo de los niveles de presión sonora registrados en el área urbana del cantón Cañar

Abstract:

Noise is a type of energetic pollution that can negatively affect ecosystems as well as endanger human health. The objective of this current project is to determine the levels of sonar pressure that can be registered in the urban area of Cañar. For this reason, certain points within the district have been selected at random and monitored, according to the political map of the town limits with the aid of the program Arcgis 10,3. All of the monitored spots have been geo-referenced, and during this process, the vehicular flow and its temporariness have also been registered. The analysis took place at what is considered to be peak hours for influx of noise, from 07:00h to 08:00h, 13:00h to 14:00h, and 20:00h to 21:00h. The equipment used was a sound level meter PCE-322A class 2, pressure levels were captured in an acoustic map which displayed the locations with the highest concentration of noise pollution. The analysis was completed over a radius of thirty unique spots located in the urban region of Cañar from the months of August to September of 2016. The obtained results showed levels of sonar pressure between 51,23dB and 82,09dB and this fact is attributed to vehicular traffic and current environmental conditions in Cañar such as wind. Furthermore, the zones with the greatest noises were those in near distance to Panamericana and Jaime Roldós (in front of the terminal), as well as Panamericana and 24 de Mayo, with noise levels above seventy five decibels. With the fabrication of the acoustic map, the first sonar pressure diagnostic of the urban region of Cañar was completed
